Bird keep routes from older bird process

[Antoine Habran]

Hello,

Sorry for my english, I hope you will understand me.

I'm using "Bird" for his OSPF implementation and I have a technical
question.

I need to keep the routes learned from OSPF after any "Bird" stop or
crashes. This can be done with the "persist" option into the kernel
configuration block in the bird.conf file.

But when I start "Bird" after a stop or a crash of the service, all
routes was forgotten.

It is possible to tell "Bird" to not erase kernel routes from older
"Bird" process?


Thanks in advance

The graceful restart feature is probably what you want:

and the "graceful restart" option at the kernel protocol.
